Star Wars Episode IV: A New Hope
Star Wars: The Force Awakens
VII was a decent movie, and I was relieved that it wasn't another flop. That said, I still don't know how this is even a question.
Both films are similar but what episode VII has that IV doesn't is nostalgia and better effects. Don't get me wrong, A New Hope is a classic but those two factors are enough for me.
Loved every single one of the new characters, along with the old ones that they brought back. The story line in episode 7 flowed nicely and would make sense even to someone who hasn't seen any of the other episodes.
